wire terminal?

I'm basically done putting my box together, but now I've come across a nice problem. I picked up a terminal cup from radio shack to put in, but there's no way that's going to work. I'll be running either 2 gauge or 4 gauge to the sub (nine.1 to a Brahma) and cannot find a terminal to do so. I've also already cut the box to put the terminal in, so I need to find something the same size or bigger (it's a rectangle, not circle).

Any kind of help is appreciated. I need to get this done ASAP since I have no audio system in my car currently and I am waiting until this box is done to have everything put in.

Re: wire terminal?

most people run the wires direct....either through the port or drill a small hole in one of the corners and seal it with caulk around the wire. as for the hole you cut....if it were mine i would install the one you bought that way the hole is covered and sealed up, but just not use it.
